Respuesta :

The areas of the circle and rectangle are

[tex]\begin{gathered} A_{\text{circle}}=r^2\cdot\pi=\pi(4)^2=16\pi \\ \text{and} \\ A_{\text{rectangle}}=lw=3\cdot3=9 \end{gathered}[/tex]

Therefore, the area of the shaded region is

[tex]\Rightarrow A_{\text{shaded}}=A_{circle}-A_{\text{rectangle}}=16\pi-9=_{}41.2654\ldots\approx41.27[/tex]

The rounded answer is 41.27cm^2
